The need for nutritious elements NP&K (nitrogen, phosphorus and potassium)
will depend on the soil type, however almost always these elements in fertilizers
help to speed the decomposition of hydrocarbons.
Soil humidity has a positive influence on oil and oil products decomposition
speed. After watering the agrochemical properties of the soil improve, particularly
the mobility of nutrients, and the microbiological and fermentation activity
increases.
